herbaceous kinds are propagated by cuttings laid on 
moist sand or inserted in a mixture of old mortar and 
sand on a greenhouse shelf. All delight in full exposure 
to sunshine. 
MIGNONETTE.—Of this favourite fragrant subject two 
sowings should be made—one in April and another in 
July for autumn flowering. As the seedlings transplant 
badly, seed should be sown where the plants are intended

Monarpa (Osweco TEA).—Increase by division of the 
roots in autumn or by seed sown outdoors in April.

of sand, peat, loam, and leaf-mould under a bell-glass in 
a temperature of 65 to 75 degrees in spring.
